HOW-TO: Open Hood Scoop for Better Air Flow

[westrock]

This is to make the vent on the top of the hood more open so that more air can flow back to the turbo.

*** Sorry about the reflections on the hood, I did this in my garage with the Sun behind me....****

This is what the hood scoop looks like from the showroom.



As you can see it is functional, but there is a shelf back there that divertes the air straightdown through a smaller vent.

Without the scoop installed you are able to see clear back to the turbo vents.





Removing The Scoop

You will need a 9mm socket wrench

Remove the two nuts located behind the hood latch.



Then push the screws up out through the holes. Use your thumb to grasp the scoop. Once the two screws clear the holes, pull up and out. The scoop will pop out.



Here you can see the scoop removed.



The air enters the scoop and is directed down through the smaller vents where it hits the inner hood skin. The air then turns 90 degrees again and heads back to the turbo vents. I would imagine all the turning kills the air flow and leaves some room for improvement.

Heres the vents that the air passes through





Modifiying The Scoop

I used a Dremel with a 1/32" thick cut-off disc. You could probably get by with a hacksaw or wire cutters. If your on this website and coming to this particular section, you should already have a Dremel

This shows the amount I chose to cut off. I basically followed the line of the vent on the bottom, so it cuts off even. I cut the center brace about halfway because that all the cut-off disc could reach. Then once I cut everything else free, I twisted the whole piece and the center brace detached nice and cleanly.




Ahh..there we go, much better now



Reinstall the scoop the same way you took it out. Place it in the hole at an angle and then push it so the screws are in the holes. Then you should be able to snap it down in place. Put the nuts back on.

Heres the modified scoop reinstalled. You can now see clear back to the turbo vents. The air has much less restriction and should maintain more velocity as your driving down the road.



Scoop still looks stock from outside, so no evident DIY workmanship here!

Thats what I figured, but it never rains in Texas, and I don't drive this car when it does. Plus water still splashes on the Turbo when it rains....just look at the underside of your hood.

Definently a worst case scenario thing, but I think its OK. And as you mentioned I know poeple have done this in the past...there just wasn't a How-To that I saw.

dam thats some crazy shine!

[IWantAn04]

paint ur garage son lol! nice write up

[Imboosted]

woah....took me like 3 min to figure out what i was looking at. LOL

I just did this and it actually helped out pretty decently. My car was already hot from driving...I did this mod...went to the grocery store and came back. I popped the hood and rather than getting a greeting of hot air I got barely any heat comming up, so it's definitely working...

[dansrt4]

Mine was ike that for close to two years so im sure its fine

[ac_srt4]

will the water kill the parts under the hood? i mean when it rains fairly heavily. i can imagine it iwll be totally wet under the hood.. i am talking about damage by cold water/rust.. or anything ucan think of?
buthowever good write up, i will do this if it doesn't damage anything

It can't be that bad because think of cars like the wrx and imprezas and etc. who have non filtered or blocked off hood scoops. Think of what it must be like once a wrx owner takes off the intercooler and does a front mount. With such a small space I can't imagine that enough water would get through to mater

[nicks2kes]

i think ill try this soon, atleast its free!!

For those concerned with water entering, maybe you can buy an additional scoop and insert it on rainy days. Should be easy enough.

water wont harm anything and I just did mine right now with a saw took like 10 min tops. I have yet to test it out but rather fun mod and very easy to do.
